XinSu International's lithium-ion battery brand is a rechargeable battery where lithium ions move from the negative to the positive electrode during discharge and reverse their direction during charging. As lightweight lithium-ion battery packs can deliver the same voltage as lead-acid batteries, the trend is that lithium-ion batteries are becoming a common substitute for lead-acid batteries.
The XinSu International Lithium Battery Charger is widely used in household electronics, portable electronics, electric vehicles, scooters, UPS energy storage systems, golf carts, multipurpose vehicles, and the aerospace industry.
Xin Su International's lithium battery charger features a three-stage charging mode: constant voltage, constant current, and trickle charging. During the constant current phase, the charger applies a constant current to the battery with a steadily increasing voltage until it reaches the voltage limit of each battery. In the constant voltage phase, the charger applies a voltage equal to the battery voltage multiplied by the number of batteries in series, as the current gradually decreases towards 0, until it reaches a set threshold of approximately 3% below the initial value for a constant charging current. Trickle charging means charging a fully charged battery at a rate equal to its self-discharge rate, maintaining the battery at its fully charged level. This state is always present when the battery is not being charged, as trickle charging will not sustain if the current is being drawn by a load; the battery will then be charged. Batteries under continuous floating voltage are also known as floating charge.
We offer chargers ranging from 3W to 1200W, and they have passed international safety certifications including UL, FCC, CA CUL, JP PSE, EU CE GS, AU SAA, RCM, C-tick, CN CCC, KR KC, UKCA, ICES, PSB, and more. We can provide an output voltage of 87V, and our products are currently suitable for battery packs ranging from 1 to 20 parallel lithium-ion batteries. Our engineers are developing more high-power chargers to meet your needs.
